<p>
The PersistFile interface is a useful interface for Bonoboizing
legacy applications, however, for new / correct applications it
is far preferable to implement the <a class="link" href="libbonobo-bonobo-persist-stream.html#BonoboPersistStream"><span class="type">BonoboPersistStream</span></a> interface,
since this will not only result in a nice clean to your application
architecture, but also allow the transparent use of local, remote,
and synthetic streams.
</p>
<p>
This interface works by connecting callbacks to the methods, in
a pretty deprecated fashion, it is probably better nowadays to
simply sub-class the BonoboXObject and override the epv methods.
Either way, after all the caveats here is an example use:
